The major global conflict that occurred between 1914 and 1918 is World War I, often referred to as "The Great War." This conflict involved many of the world's great powers, divided into two main alliances: the Allies and the Central Powers. It was characterized by trench warfare, significant loss of life, and widespread destruction, fundamentally altering the geopolitical landscape. The war saw the introduction of new military technologies and tactics, leading to unprecedented levels of carnage. Its culmination led to the Treaty of Versailles, which reshaped borders and imposed harsh reparations on Germany, setting the stage for future conflicts.
